A widget that provides a user interface for the user to enter a search query and submit a request
to a search provider.
When a View implements this interface it will receive callbacks when expanded or
collapsed as an action view alongside the optional, app-specified callbacks to MenuItemCompat.OnActionExpandListener.
See MenuItemCompat for more information about action views.
See ActionBar for more information about the action bar.
